Specification of Letters Patent No. 1,083, dated February 19, 1839;Antedated November 23, 1838'.

To all whom it may concern:

Be it known that I, AUGS. V. H. WVEBB, of the city, county, and State ofNew York, have invented a new and improved burner, together with a glassor chimney of a peculiar construction, for burning a composition which Idenominate camphene; and I do hereby declare that the following is afull and exact description thereof, reference being had to the annexeddrawings of the same, making part of this specification.

My invention consists in the construction of a lamp or burner formed bytwo frustums of cones, one within the other, connected at the bottom andapproaching each other at the top and which may be furnished with acontinuous circular wick by inserting. between the upper edges of saidfrustums of cones, strips of cotton flannel or other materials; or whichmay be used for burning gas, by placing between said upper edges aperforated ring instead of the wick or otherwise, and which may itselfbe of suflicient capacity to constitute the reservoir or may beconnected (by a tube L see Figure 4 of the accompanying drawings) with afountain or reservoir of other shape, with a feed pipe N for receivingthe material for burning, and with screws, slides or any other mode ofraising or lowering the chimney, which, regulates the external draft.

I constructmy burners A, by connecting two frustums of cones together atthe bottom as represented in the drawings marked at B, leaving themdisconnected at the upper edge C, to admit the wick W or a perforatedring M for burning gas, see Fig. 5 of accompanying drawings. Each stripof wicking is introduced separately between the opening or upper edgesof said frustums of cones by means of a narrow strip of tin until saidopening is filled, thus forming one continuous wick. Also, a glass tubeor chimney D, so constructed as by its elevation or depression toregulate the light produced by this or any other burner adapted to itsuse, and shaped either as a straight or bulbous tube, with a neck orsudden contraction in its diameter of half an inch more or less near thebottom so that said neck shall be in the clear, inside, about threeeighths, of an inch larger than the top of the burner for which it isintended and from the inner part of which neck or contraction l, aflange J, is projected outward and downward nearly corresponding withthe form of the burner and about one inch more or less at such an angleas to regulate the draft of air to the outside of the flame; the chimneyor glass tube D, being as large or a little larger at the top than atthe bottom above the neck, and flaring off at the upper edge.

Figure 1, in the drawings represents a perspective view of the burner.Fig. 2, represents a sectional view of the same. Fig. 3, represents onemode of raising or lowering the glass or chimney to wit, by means ofnuts and screws, on which, rests the ring or frame supporting thechimney.

The same letters of reference on the several figures refer to the sameparts as E, the circular ring or frame sustaining the glass chimney; K,the ears of the ring or frame; G, the screws; F, the nuts or buttons. Byturning the nuts or buttons F, on the screws G, the glass chimney D, israised or depressed.

That I claim as my invention and desire to secure by Letters Patentis 1. The construction of the burner with a circular and continuousapertures between the upper edges of the frustums of two cones to admiteither a continuous circular wick in the form of a hollow frustum of acone or a circular perforated ring or plate as before described andwhether to be used for burning camphene, gas, or any other article.

2. The chimney, being shaped either as a straight or bulbous tube with aneck or sudden contraction in its diameter of half an "inch more or lessnear the bottom, so that said neck shall be in the clear, inside, aboutthree eighths of an inch larger than the top of the burner for which itis intended and from the inner part of which neck or contraction I, aflange J, is projected outward and downward about one inch more or less,said chimney being as large or a little larger at the top than at thebottom above the neck, and flaring off at the upper edge, or of anyother form substantially the same, and to be used with said burner orany other burner and whether made of glass or any other ma terial.

3. Regulating the light by the raising or lowering of the chimney in themanner before described or by any other substantially the same.

4:. And the combination of all or any of the parts hereinbefore claimedfor the production of artificial light.
